Hi. Yes, that termination is acceptable. The 1.5V supply is always sourcing
current (no need for a source/sink). This would be fine if you only had a
relatively small number of lines to terminate. If you had a lot of lines,
the drawbacks could be tough to swallow.

The drawbacks include a higher power consumed in the thevenin termination
(always drawing "idle" currents between 1.5V and ground) and it takes twice
as many resistors. The advantages are if you have a small number of lines,
you don't need to design any fancy (source/sink) power supply circuit.
